I have a workaorund and a fix for this bug. The bug is due to missing UCM2 folders and config files, which are now available on git hub.
The missing folders are: - /usr/share/alsa/ucm2/chtmax98090/ : it can be retrieved from https://github.com/alsa-project/alsa-ucm-conf/tree/master/ucm2/chtmax98090 - /usr/share/ucm2/codecs/max98090/ : it can be retrived from https://github.com/alsa-project/alsa-ucm- conf/tree/master/ucm2/codecs/max98090 After adding the above two folders and a reboot, the sound works fine.
